That looks like fun. Gouging your hand into a display unit, sinking into the colored lights like Ewan McGregor into the carpet during his heroin-fuelled trip in Trainspotting. Impress, as the flexible display is called, runs on Arduino and sensors.

It's the work of German designer Silke Hilsing, who put sensors in between layers of foam, so when someone touches the foam it turns an overhead projector on, which beams colored lights down. The harder someone presses down on the foam, the more colors and light they can see.
